FusionAuth version 1.23, released on January 11, 2021, introduces new features and resolves issues from previous versions. Notable additions include two new customer support roles: the read-only `user_support_viewer` for new employees to learn the admin UI without making changes, and the `user_support_manager`, which allows user management actions without privilege escalation capabilities. The update also integrates LinkedIn as a new identity provider, enabling users to register or log in using their LinkedIn accounts, which is beneficial for applications targeting professional audiences. Additionally, the release addresses ten bug fixes, including enhancements to the .NET Core client library, SAML signature validation, and IP address display for FusionAuth clusters. Users are encouraged to review the release notes for a comprehensive list of changes and to follow the upgrade guide for self-hosted instances, while FusionAuth Cloud users can request upgrades through their account dashboard.
